Drop the open-coded MAC assignment from net_init_nic and replace it with
standard qemu_macaddr_default_if_unset which is also used by qdev. That
avoid creating colliding MACs when instantiating NICs via different
mechanisms.
This change requires to store the MAC as MACAddr in NICInfo, and the
remaining nd_table users need to be updated.
Based on suggestion by Peter Maydell.

This aligns the code to what the documentation claims: Allow everything
but requests that would have to be routed outside of the virtual LAN.
So we need to drop the unneeded IP-level filter, allow TFTP requests,

-machine somehow suggests that it selects the machine, but it doesn't.
Fix that before this command is set in stone.
Actually, -machine should supersede -M and allow to introduce arbitrary
per-machine options to the command line. That will change the internal

stable.

This patch adds support for a usb-redir device, which takes a chardev
as a communication channel to an actual usbdevice using the usbredir protocol.
Compiling the usb-redir device requires usbredir-0.3 to be installed for
the usbredir protocol parser, usbredir-0.3 also contains a server for
redirecting usb traffic from an actual usb device. You can get the 0.3
release of usbredir here:
http://people.fedoraproject.org/~jwrdegoede/usbredir-0.3.tar.bz2
(getting a more formal site for it is a WIP)
Example usage:
1) Start usbredirserver for a usb device:
sudo usbredirserver 045e:0772
2) Start qemu with usb2 support + a chardev talking to usbredirserver +
a usb-redir device using this chardev:
qemu ... \
-readconfig docs/ich9-ehci-uhci.cfg \
-chardev socket,id=usbredirchardev,host=localhost,port=4000 \
-device usb-redir,chardev=usbredirchardev,id=usbredirdev

This patch implements MMU faults caused by TTE.NFO and TTE.E:
- access other than nonfaulting load to a page marked NFO should
raise data_access_exception
- nonfaulting load to a page marked with E bit should raise
data_access_exception
To distinguish nonfaulting loads, this patch extends (abuses?) the rw
argument of get_physical_address_data(). rw is set to 4 on nonfaulting
loads.
